PayPal Scam?

So late last night I got $.02 deposited in my PayPal account. It is from a person that I don't know at all. I tried looking them up on LinkedIn and Facebook and I am not associated with anyone with that name. Has anyone heard of a PayPal scam that this could be?

refund it telling you don't know where its from.

That is a good idea, I don't know why I didn't think of that in the first place. I guess I was thinking that I didn't want the person to know I was real, but he must already know I am real because the transfer went through.

Thanks
